The reasons
Cofounder gives a founder agents for sales, marketing, design and operations in one workspace. These six limits come from its own pricing page, docs and terms.
The entry price for Cofounder Pro, per its pricing page. There is no free plan, only a 7-day free trial that lists a design system builder, landing page hosting, and strategy and analysis.
“Cofounder is not your core product builder,” say its Cofounder docs home. The app, its database, login and hosting stay with your own coding agent or engineers (What Cofounder does).
“Each organization requires its own subscription,” per the onboarding docs, with no price given for the second one. At Pro’s list price, three ideas would cost $4,320 a year.
The pricing page doesn’t say how much usage $120 includes, and Cofounder’s terms bill usage-based charges in arrears at rates it doesn’t publish.
The listed starting price was $20 a month with usage included on July 8, 2026 and $120 by September 2. The two plans may not include the same usage.
The terms put the consequences of agent actions on you “whether or not you have reviewed or approved such actions,” while the homepage says “nothing ships without your approval” and the deploy docs show an Approve step before staging.
Cofounder’s pages also disagree with each other. The students page still offers Pro at $20 a month with usage included, and the product that launched in May as “idea to live product” is now scoped to the company around your product. Cofounder 1 went into a planned sunset on April 29, 2026, with access kept for exports. Check the date on any Cofounder price a review quotes, ours included.
Among the tools that build the product, the fee is what separates them as sales grow: at $2,000 a month, Polsia’s 3% costs $720 a year and NanoCorp’s 20% costs $4,800. Card processing is separate; on DoAny, Polsia, Atoms and Runable it is Stripe’s own (2.9% + 30¢ per US card charge).

| Option | Entry price | Best for | Watch out for |
|---|---|---|---|
| Cofounder (today) | Pro $120/mo; a 7-day free trial, no free plan. (Cofounder pricing) | Founders who build the product elsewhere and want agents for the company around it | Its docs say it isn’t your core product builder; one subscription per company; usage terms unpublished |
| DoAny | Free $0 with no card, any number of companies, and Free can sell; Pro from $25/mo. (DoAny pricing) | Founders without a product yet who want it built, hosted and selling, and several ideas on one plan | One agent directed by chat, no big connector marketplace, no native mobile apps; custom domains need Pro |
| Polsia | Standard $20/mo for 1 company; Pro $50/mo with Meta Ads. (Polsia pricing) | An agent that builds and runs the company, ads included | A 3% platform fee on every charge, and a 31-day settlement period rolling out |
| Atoms | Free $0; Pro $20/mo, or $15.80/mo billed yearly. (Atoms pricing) | A team of agents that researches, builds the app and markets it with SEO pages and Google ads | A live app draws on a separate Cloud & AI balance with no published rate card |
| Runable | Free $0 without website building; Pro $20/mo. (Runable pricing) | One general agent for web and native iOS and Android apps, plus ads and outreach | Website and app building start on Pro; no published fee rule for your sales |
| Lovable | Free $0; Pro $25/mo for 100 monthly credits. (Lovable pricing) | The product alone, to pair with Cofounder or to own the build yourself | It builds the product, not the company; built-in payments need Pro |
| NanoCorp | Founder $30/mo; a 3-day trial at $0. (NanoCorp pricing) | Hands-off agents that build and sell for several businesses | A 20% fee on withdrawals of your sales |
The shortlist
Best for: founders with no product yet. Cofounder’s docs leave the product to your own coding agent or engineers; DoAny builds and hosts it, with accounts, a database and Stripe checkout built in, no API keys to paste. Annie researches your idea and market first, then handles daily growth work after launch.
Price: Free is $0 with no card: 5 credits a day, up to 30 a month, shared by every company you start, unlike Cofounder’s one subscription per company. Pro starts at $25/mo for 100 monthly credits and adds a domain you own. DoAny takes 0% of your sales; Stripe’s processing fees still apply (DoAny pricing; DoAny Terms).
Watch out for: one agent directed by chat, with no drag-and-drop editor and no connector marketplace; Annie reaches other services with a backend function and your API key. No cold-email inboxes, domain purchase or LLC filing. No native iOS or Android apps. The checkout on the sites DoAny builds is Stripe only, with no coupons at the moment.
Moving from Cofounder: DoAny imports existing code and database records, so hand it the repositories and Supabase data you get out instead of starting over. The step-by-step order is in DoAny vs Cofounder.
Polsia is the closest match to Cofounder’s original promise: an agent that builds the product and runs the company, including outreach and, from Pro, Meta ads.
Watch out for: Polsia “takes a flat 3% platform fee on every charge” on top of Stripe’s fees, and it is rolling out a 31-day settlement period before payouts, per its payouts help. Standard covers one company.
Price: Standard $20/mo (20 credits, 1 company, no Meta ads), Pro $50/mo (50 credits, up to 3 companies, Meta ads), Max $100 or $200/mo (up to 10 companies).
Atoms sells a named team of AI agents that researches an idea, builds and hosts a web app, then markets it with SEO pages and Google Search ads (working with agents). Payments go to your own Stripe account, and its e-commerce page says you “keep full revenue minus standard Stripe processing.”
Watch out for: hosting, the database and AI features in a live app draw on a separate Cloud & AI balance, in dollars, with no published rate card (wallet help). Build credits can’t be topped up; you move up a plan instead.
Price: Free $0 (15 credits a day, up to 25 a month); Pro $20/mo for 100 credits, or $15.80/mo billed yearly, with a custom domain and Atoms Cloud; Max from $100/mo.
Runable is a general AI agent. On Pro it builds websites and web apps with a database, analytics and Stripe, plus native iOS and Android apps, and it makes slides, images, video and research documents. Its Grow features add paid ads, social posting and cold outreach.
Watch out for: the Free plan doesn’t include website or app building. Runable doesn’t publish whether it takes a fee on your sales, and its top-up prices aren’t published.
Price: Free $0 (1,500 credits a day); Pro $20/mo for 25,000 credits a month plus daily credits, or $180 for the first year billed yearly; Max $100/mo.
Lovable builds and hosts web apps from chat. It is the natural pair for Cofounder, whose docs send the product to “your preferred coding agent, IDE, or engineering team,” or a way to own the build yourself and skip the $120.
Watch out for: it builds the product, not the company around it. Its payments docs say “built-in payments require a paid Lovable plan”; on Free you can connect your own Stripe account instead. It adds no platform fee.
Price: Free $0; Pro $25/mo for 100 monthly credits, with custom domains.
NanoCorp’s agents build and sell for you, and the Founder plan covers several businesses with custom domains.
Watch out for: a “20% fee on withdrawals” of your sales. The 3-day trial pauses checkout, email and agents when it ends.
Price: a 3-day trial at $0 with no card; Founder $30/mo for 30 credits.
Decision rules
Swipe to compare every column.
| If you need | Pick | Because |
|---|---|---|
| The product built and the business run, with nothing taken from sales | DoAny | Accounts, a database and Stripe checkout are built in, you can sell on the Free plan, and DoAny takes 0% of your sales; Stripe’s processing fees still apply. |
| Several ideas on one budget | DoAny | Every plan, from $0, runs every company you start on one credit balance; Cofounder needs a subscription for each. Free’s 30 credits a month are shared across them. |
| An agent that runs Meta ads for you | Polsia Pro | Meta ads start on Pro at $50/mo; every charge pays 3%. |
| Research, build and Google Search ads | Atoms | Its agents cover research, the app, SEO pages and search ads, from $20/mo. |
| Native iOS and Android apps as well as web | Runable Pro | Pro includes Android and iOS app building; DoAny builds web apps only. |
| Only the product, alongside Cofounder | Lovable | It builds and hosts the app Cofounder won’t, from $25/mo with built-in payments. |
| Go-to-market agents for a product you already build | Stay on Cofounder | That is the job its docs describe, with the widest integration list here. |
| Hands-off agents, and a cut is acceptable | NanoCorp or Polsia | Both build and sell for you; NanoCorp takes 20% of withdrawals, Polsia 3% of each charge. |
A valid choice
Cofounder is “built for people who can build their core product elsewhere,” especially B2B founders with their own codebase (Cofounder docs: what Cofounder does). It reads your repository and issues and hands product work to your coding agents as a brief.
Its integrations page names about fifty services, from Slack, Gmail and Notion to Attio, PostHog and Ramp, plus custom MCP servers with access set per agent.
Agent inboxes sit on your own domain, and warmup has a “21 day minimum,” 28 days recommended, before outreach starts (inbox docs).
Cofounder buys and manages domains in the app (domains docs) and runs a guided US LLC filing with Ramp, which “can involve filing costs” (roadmap docs).
Leaving cleanly
This applies whichever alternative you choose. Moving to DoAny specifically? The step-by-step order is in DoAny vs Cofounder.
Swipe to compare every column.
| Asset | What Cofounder documents | Do this before you cancel |
|---|---|---|
| Product in your own repository | It stays in “the codebase and engineering workflow you control.” (What Cofounder does) | Nothing to move. Remove Cofounder’s GitHub app from the repository when you leave. |
| Managed app and marketing repositories | An org admin can send a GitHub user collaborator invites from Settings, then Advanced. (GitHub docs) | Accept the invites and clone both repositories. |
| Managed Supabase data | Users “are not invited into Supabase yet.” (Managed services docs) | Ask Cofounder how to export the data before you cancel. |
| Library files | Download from each file’s menu when a download link is available. (Library docs) | Download the files you want to keep. |
| Domains bought through Cofounder | The Domains page covers buying, importing, transfers in, DNS records and auto-renew. (Domains docs) | Point DNS at the new host, and ask support how to move the domain out before you cancel. |
| Stripe | Your own account; an admin pasted its keys into Settings, then Payments. (Payments docs) | Nothing moves. Roll the secret key you gave Cofounder in your Stripe dashboard. |
| Plan and account | Written notice at least 7 days before the term ends; no refunds for paid time; 30 days to export after the account ends, then deletion. (Cofounder Terms) | Export first, then send notice early. |
Common questions
One that builds the product, since Cofounder’s docs say it isn’t your core product builder. DoAny builds and hosts a web app with accounts, a database and checkout, keeps working on the company, and starts free. Atoms and Runable (Pro $20 a month each) also build apps and market them. Polsia (Standard $20 a month) builds and runs the company but takes 3% of every charge. To keep Cofounder and add only the product, Lovable Pro is $25 a month.
Cofounder has a 7-day free trial but no free plan; Pro is $120 a month. DoAny Free is $0 with no card, 5 credits a day up to 30 a month, and it can go live and take real card payments once you finish Stripe’s verification. Atoms and Lovable also have $0 plans, though Lovable’s built-in payments need Pro, and Runable’s Free plan doesn’t include website or app building. NanoCorp offers a 3-day trial.
Polsia takes a 3% platform fee on every charge, and NanoCorp takes 20% of what you withdraw. DoAny takes 0% on every plan, Free included, and Atoms and Lovable list no platform fee; Stripe’s processing fees still apply on all of them. Cofounder lists no fee on your sales. Runable doesn’t publish whether it takes one. Prices checked September 27, 2026.
Yes, and Cofounder’s docs point that way: your product stays with “your preferred coding agent, IDE, or engineering team,” and Cofounder runs the work around it. At list price that is $120 a month for Cofounder Pro plus $25 for Lovable Pro, $145 a month in all, before any usage either bills beyond its plan. DoAny covers both jobs from $0, or $25 a month on Pro.
Collect the code first: a product in your own repository is already yours; an admin can invite your GitHub account to the repositories Cofounder manages. Download Library files and ask how to export data from the managed Supabase project, which users aren’t invited into yet. Give written notice 7 days before your term ends; paid time isn’t refunded, and you get 30 days to export after it ends. DoAny imports existing code and database records, so you don’t start over.

Put the evidence to work
Cofounder leaves the product to you; DoAny builds and hosts it, then keeps working on the company. Start free with 5 credits a day and no card, test checkout with Stripe test cards, then go live and take real payments on the same Free plan. Not sure yet? Read DoAny vs Cofounder first.
